Is a Dana 60 trac-loc a usable diff in a high performance application? Is it capable of handling high 10's? Are the rebuildable?

No they are only good up to about 275 to 300 HP. Keep looking in the local yards,Dana 60 powerlocs trun up every now and then.

the trac loc is what the clutch type, the power lock is the bolt together style? i have the clutch type and going 11.80 i think im pushing a little more than 300 hp. i pretty much beat the hell out of it and have never had a problem. the guy that built my dana did want to use the power lock but you cant get them new. and a detroit locker is over 500 i think. so i settled for this. he told me id be fine, and if i wanted it tighter i could just tighten up the clutch pack, but i like it. its a tuff unit, you can buy them new from strange and others for around 285 bucks. my bud also used a stock one and rebuilt it and added 35 spline side gears his car with a stick went low 12's and yanks both wheels, no problems yet. i could be thinking of the wrong unit though, i guess.

No, i think you're talkin about the same unit. The trac loc has 2 spider gears and a power loc has 4. I thought strange sells both types.

right, the power-lock can be identified by all of the bolts on the opposite side of the ring gear

I love Fords, but their factory Trac-Loc unit is a piece of garbage. After 100,000 miles, they're toast. Do yourself a favor, and buy a Detroit Locker or a selectable locker ( OX, E-Locker, ARB ) if you're going racing or don't want to be the guy leaving one leggers all over town.
